Custom Elements

How to register img-lazy component as a custom element

This custom element is useful to increment the Performance of a application because use the defer offscreen hability, is compatible with SSR and very useful for SEO, the images are wrapped in a figure element and the description in a figure-caption element also.

• In a SSR application:

import { ImgLazyComponent } from './modules/cap-responsive/custom-elements/img-lazy/img-lazy.component';
import { PLATFORM_ID, Inject, Injector } from '@angular/core';
import { isPlatformBrowser } from '@angular/common';
...

@Component({
  selector: 'app-root',
  templateUrl: './app.component.html',
  styleUrls: ['./app.component.scss']
})
export class AppComponent {
  constructor(
    private injector: Injector,
    @Inject(PLATFORM_ID) private platformId: string) {
      const { createCustomElement } = require('@angular/elements');
      if (isPlatformBrowser(this.platformId)) {
        // Register Custom Elements and Web Components
        const elements: any[] = [
          [ImgLazyComponent, 'img-lazy-element']
        ];        
        for (const [component, name] of elements) {
          const el = createCustomElement(component, { injector: this.injector });
          customElements.define(name, el);
        }
    }
  }
}

• In a non SSR aplication:

import { ImgLazyComponent } from './modules/cap-responsive/custom-elements/img-lazy/img-lazy.component';
import { createCustomElement } from '@angular/elements';
...

@Component({
  selector: 'app-root',
  templateUrl: './app.component.html',
  styleUrls: ['./app.component.scss']
})
export class AppComponent {
  constructor() {
    // Register Custom Elements and Web Components
    const elements: any[] = [
        [ImgLazyComponent, 'img-lazy-element']
    ];        
    for (const [component, name] of elements) {
        const el = createCustomElement(component, { injector: this.injector });
        customElements.define(name, el);
    }
  }
}

Update the main.ts file

For wait for Web Components are ready are required the next configuration:

import { enableProdMode } from '@angular/core';
import { platformBrowserDynamic } from '@angular/platform-browser-dynamic';

import { AppModule } from './app/app.module';
import { environment } from './environments/environment';


declare global {
  interface Window {
    WebComponents: {
      ready: boolean;
    };
  }
}

if (environment.production) {
  enableProdMode();
}

function bootstrapModule() {
  platformBrowserDynamic().bootstrapModule(AppModule)
    .catch(err => console.log(err));
}

document.addEventListener('DOMContentLoaded', () => {
  if (window.WebComponents.ready) {
    // Web Components are ready
    bootstrapModule();
  } else {
    // Wait for polyfills to load
    window.addEventListener('WebComponentsReady', bootstrapModule);
  }
});
